All other setting options for the automatic
climate control can be found at "Climate"
and in the menu on the Control Display,
refer to pages 90 and 91.
The current setting for air distribution is dis-
played on the Control Display.
A congenial climate
To use the automatic function, press the
AUTO button. Select an interior tempera-
ture you find pleasant.
The following section contains more
detailed information on the available set-
ting options.
The cooling function is only possible with
the engine running.
AUTO program
The AUTO program adjusts the
air distribution to the wind-
shield and side windows,
towards the upper body and footwell as
well as the air volume, while also using your
preselected temperature setting as the
basis for adjusting the interior climate to
adapt to external seasonal influences.
The cooling function comes on automati-
cally when you select the AUTO program.
At the same time, a condensation sensor
controls the program in such a way that
window condensation is prevented as far
as possible.
Temperature adjustment
The figures on the display pro-
vide a general indication of inte-
rior temperature. A pleasant
adjustment is 727/226.
When you start the vehicle, this system ensures that the selected tempera-
ture is achieved as quickly as possible. It
then maintains this temperature, regard-
less of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and front side win-
dows.
Adjusting air volume manually
You can adjust the air volume
by turning. You can reactivate
the automatic mode for the air
volume with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature set-
ting. Depending on the weather, the wind-
shield may fog over briefly when the engine
is started.
The cooling function comes on automati-
cally when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The system switches to the
recirculated-air mode and the
air flows at maximum air volume only from
the vent outlets for the upper body area.
For this reason you should ensure that
these vent outlets are open before select-
ing this program.
AUC Automatic recirculated-air
control
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-

A congenial climate
90 rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle continuously
>Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes
>Left indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is continuously blocked.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing
the air volume as required.
The recirculated-air mode should not be
used over a longer period of time, as the air
quality inside the vehicle deteriorates con-
tinuously.<
Residual heat mode
If you press this button with the
engine switched off, the system
uses the warmth stored in the
engine to heat the interior, for
instance, while the vehicle is
stationary at a school to pick up a child.
You can adjust the automatic climate con-
trol settings as of ignition key position 2.
Provided that the engine has warmed to its
normal operating temperature and the bat-
tery is charged, you can use this function
for up to 15 minutes after switching off the
ignition. The LED within the button lights up
to confirm compliance with both of these
conditions.
Switching off automatic climate
control
The air volume, the heater and
the cooling function are all
switched off. You can restart
the automatic climate control
by pressing any of its buttons
except the REST button.
Settings using Control Center
Ignition key:
>On vehicles with separate drives for
audio CDs and navigation DVDs, igni-
tion key in position 2
>On vehicles with one drive for audio
CDs, ignition key in position 1.
Control Center, for principle details, refer to
page 16:

self and also individually adjust the air tem-
perature in the upper body area.

road surface. This phenomenon is referred
to as hydroplaning, and is characterized
by a partial or complete loss of contact
between the tires and the road surface, ulti-
mately undermining your ability to steer
and brake the vehicle.<
The risk of hydroplaning increases as the
tread depth of the tires decreases, also
refer to Tire tread on page 167.
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Braking safely
Your BMW is equipped with ABS as stan-
dard. The best way to achieve optimized
braking response from the ABS is to apply
maximum pressure to the brake pedal in
situations where this is required: panic
stops. Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a minimum
of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.<
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to ensure
that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to
ensure that full braking efficiency will then
be available when you need it.
Hills
To prevent overheating and thus
reduced efficiency of the brake sys-
tem, downshift to a gear in which only min-
imal brake applications are needed when
descending long or steep downhill
stretches. Even light but consistent pedal
pressure can lead to high temperatures,
brake wear and possibly even brake fail-
ure.<
You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
page 59. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never drive with the clutch pressed
or allow the vehicle to coast with the
transmission in Neutral – or with the engine
switched off – there is no engine braking
when the transmission is in Neutral, and no
power assist for brakes and steering when
the engine is not running.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion on brake rotors
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are
less frequent, there is an increased ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimum
pressure which must be exerted by the
pads during brake applications to clean the
rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a pul-
sating effect that even extended applica-
tion will fail to cure.

Weather Band*
Weather Radio is a service of the National
Oceanic and Atmospheric Administration –
NOAA – of the U.S. Department of Com-
merce. Weather messages are repeated
every four to six minutes and are routinely
revised every one to three hours, or more
frequently if needed. Most of the stations
operate 24 hours daily. During severe
weather, National Weather Service fore-
casters can interrupt the routine weather
broadcasts and substitute special warning
messages. If you have a question concern-
ing NOAA Weather Radio, please contact
your nearest National Weather Service
Office, or write to National Weather Service
– Attn: W/OM11 –, National Oceanic and
Atmospheric Administration, 1325 East-
West Highway, Silver Spring, MD. 20910.

Inserting CD magazine
Push in the CD magazine as far as possible
in the direction of the arrow.
The CD changer automatically reads in the
inserted CDs and is then ready for opera-
tion.
Notes
For correct playback of MP3 content, the
MP3 data should have been produced with
the Fraunhofer codec.
Good playback quality is achieved with a
data transfer rate of 192 kBit/s, however it
should be at least 128 kBit/s.
Safety notes
The BMW CD drives are Class 1 laser
products. Do not operate if the cover
is damaged, otherwise severe eye damage
can result.
Do not use self-recorded CDs with labels
applied as these can become detached
during playback due to the development of
heat and cause irreparable damage to the
device.
Only use round CDs with a standard diam-
eter of 4.7 in/12 cm and do not play CDs
with an adapter, e.g. maxi CDs, as other-
wise the CDs or the adapter can jam and
may no longer be ejected.
Do not use a combined CD/DVD, e.g.
DVD
Plus, as otherwise the CD/DVD can jam
and is no longer ejected.<
Malfunctions
To prevent illegal CD copying, manufactur-
ers often use copy protection. This can
mean than some CDs cannot be played or
only to a limited extent. In this case, please
contact the CD dealer or manufacturer.
You may experience playback problems,
such as skips, when using CD-Rs/CD-RWs
that you have copied at home.
If the CD that you have loaded in the drive
does not play, check to ensure that the CD
has been inserted correctly and inspect it
for signs of defects.
High levels of humidity can lead to conden-
sation on the laser's scan lens and tempo-
rarily prevent it from reading the CD.
Keep CDs away from magnetic fields as
created, e.g., by loudspeakers.
Always hold CDs by the edges; do not
touch the reflecting CD memory surface.
